El Torcal de Antequera Nature Reserve is in the municipality of Antequera, in the centre of the province of Málaga. It forms a part of the limestone mountain chain that crosses the heart of the province, and creates a natural barrier between the Vega de Antequera (plains) and the Montes de Málaga. It is visible practically throughout the province. It is separated from another nearby formation of limestone mountains known as the Sierra de Cabras, by the mountain pass known as the Ass’ Mouth.
